(You will need to understand "Pin Ying" to continue.)
A bear is la1 ba3 ba3 in the forest. When he is done, he sees a rabbit coming by.
"Hey Rabbit, do you think it is bad to get ba3 ba3 on the fur?" asks the bear.
The rabbit says, "No, it is fine!"
So the bear grabs the rabbit and uses him to ca1 ba3 ba3.
